The monitor is probably on protection.

To start unplug monitor from power and from computer and test computer with different monitor to find out if it is monitor or computer fault.

If it is computer fault and no video signal , then test:

  • Video cable.
  • Video adapter on PC (sometimes integrated on motherboard)
  • Motherboard.

If it is monitor fault , then the monitor is on protection.

When on protection you keep having a flashing led on front of the monitor , and monitor turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or a broken contact, identified an internal fault and kicked in , starting the flashing light.


If you are in situation one, then the monitor will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occurr are a blown capacitor on power board, faulty inverter board, faulty input board, or a fault on LCD Digital Controller board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing statebecause of the video cable.

Try moving the video cable, and if the cable is not built in, then also try a replacement cable.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

I purchast x2gen manitor madel mw19u 4 years ago and it stopt working help!


4 years monitor will more likley to have bad caps by now, which is very common problem as you can see in my albums, that will be the first thing to look for.
If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Message saying going off to sleep when you turn on the monitor.


Does it do the same when attached to another PC? We want to make sure it is not PC's video card not sending the signals to the monitor. VGA cable are seated properly?
If it is the monitor, then first place to look will be the bad caps as hsown in my pictuers here:

Why my monitor screen has gone


well first check to make sure the cables are plugged in and not frayed or kinked. then check to see that the cord from your manitor to your tower (its normally blue) is screwed in because if it is not it will have a hardtime finding connectivity

Hope this helps!!

My newer flat screen monitor went black but works fine when hooked up to another computer and I have an older monitor that I hooked up and the older one works fine...??


That sounds like a display/resolution setting problem on your PC. I doubt there is anything actually wrong with the PC or the monitor, since both work with different combinations, so its most likely just a setting.

Some monitors don't display anything when they get a signal/resolution that is not compatible with their displays. I would try changing the display settings on your computer with your old monitor, then switch monitors and see if your newer monitor works.

Here's how to adjust the display resolution:
If in XP, right-click on the desktop and go to Properties, and select the tab for display settings and adjust/lower the resolution. If in Vista/Win7 right-click the desktop and select Screen Resolution/Display Settings and adjust it there.

Att:Monit

Not too many manufacturers are providing schematic for their product. But you probably can try eservice.com if they have. you have to sign up to download. You did not mention the model of your manitor. However, if your monitor is old enough, it probably needs CCFL replacement. The ends of the tube usually get blacken when out just like the ordinary flourescent lamp. If still new, then it could be the CCFL driver (pwr supply).
